The surgery was performed by Dr. Tom Bryan of West Covina, the same surgeon who repaired Herrin’s injured left shoulder this past October, with Bryan happy with how the procedure turned out.

“The volar fascia was thick and tight, and it definitely needed to be released,” Bryan said in a team release from Yamaha. “Everything went perfectly with the procedure.”

Bryan made incisions on both the outside and backside of Herrin’s right forearm, in a procedure that has become fairly common among motorcycle racers who experience arm pump - which is basically pressure and weakness in their forearms under the duress of racing.

Herrin only had the surgery done on his right forearm.

“It’s worse in my right arm than it is in the left, for whatever reason,” said Herrin, who won the first of two Superbike races at Daytona on March 8. “It really bothered me at Daytona, under braking and also while I got on the gas. That finally convinced me to have the surgery done. And, after what Dr. Bryan found when he went in there, I’m really glad I did it. Now, I’m looking forward to getting back on the bike as soon as I can.”

Herrin says the recovery time will be two to four weeks, so he’ll be fully fit in time for the next round of the series – currently scheduled for Road America in Wisconsin the weekend of May 31- June 2.
